Common Mode Chokes Procurement Notes

Verify the specific part number ET3542-057 against official Triad Magnetics documentation to ensure correct specifications. Confirm that the required inductance, current rating, and physical dimensions align with your design constraints. Check for updated certification status and RoHS compliance before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when a 6 mH inductance at 10 kHz is required for two-line power filtering. Ensure the PCB layout accommodates the vertical package dimensions of 38.00mm x 26.00mm x 45.00mm. Verify that the circuit operates within the -20°C to 105°C temperature range and does not exceed the 3.5A current rating or 250V AC voltage limit.

Common Mode Chokes Part Context

This component belongs to the ET series of common mode chokes from Triad Magnetics. These components are engineered for general-purpose EMI filtering in power lines. The ET series offers various inductance and current ratings to suit different power handling requirements while maintaining standard through-hole compatibility.

Common Mode Chokes Replacement Considerations

Consult Triad Magnetics datasheets for direct substitutes within the ET series. Verify that any alternative part matches the 6 mH inductance, 3.5A current rating, and vertical package dimensions to ensure mechanical and electrical compatibility.
